Propulsion Research on the Variable Isp Tandem Mirror Plasma Rocket

Seeing as ATS has begun releasing Sgt Clifford Stone's collection of FOIA documents... it seems like a perfect time to toss some of the ones collected by associates of Pegasus Research Consortium while researching the various topics John Lear, myself and others cover in the various threads...

I have over a thousand collected already. These are all publicly available from various government organizations.  I am going to store the files on my server (well until I see problems with bandwidth :P) 

The reason for this is that several times in the past I have linked people directly to a pertinent document only to have it pulled, most likely due to the number of hits they received to a paper that would have normally remained obscure.

The papers I will start with are ones discovered while working in this thread originaly started by spikedmilk...
The Rainbow Conspiracy - what is this picture?

This paper deals with an offshoot technology of the Tandem Mirror Fusion Project from Lawrence Livermore National Laboratory... (see the thread for the background work)

Title: Propulsion Research on the Variable Isp Tandem Mirror Plasma Rocket
Date of Report: Feb 7, 1994
Source: MIT


This report describes the progress made in the past two years as well as the overall picture of this research. In the past years Several milestones have been achieved towards the realization of a practical space plasma thruster from the tandem mirror rocket experiment, i.e- the specific impulse, thrust, energy conversion efficiency, and mass flow-rate have been determined. The experiment operates at 9.4 kW of input power at an rf-to-plasma efficiency of 68%; The ion temperature is 172 eV ( 2,000,000 K ) which gives an I., of 12,852 s. The thrust is 76 mN (milli Newton) which is a high value for a low input power (9.4 kW) and very high I., ( 12,852 s ). The radiation loss was found to be very low. Most important, these results fall within our prediction.

A key advantage of this propulsion system is its high energy density that can be contained in the plasma. A flight system design and analysis has shown that the present experimental device can handle a power level in excess of 10 MW, resulting in specific weights as low as 0.04 kg/kW. The overall specific weight of a space vehicle for a piloted Mars mission, including nuclear power and power conditioning equipment, is only 8 kg/kW. This is a conservative
value which can be further reduced to 6 kg/kW.

A\ 150 day trip to Mars ( 180 day round trip including 90 days stay over ) can be achieved with only 10 MW\ of power. The trip time has been optimized by varying the I., and thrust to meet a required returned mass of 57.000 kg. In that study an efficiency of only 50% was assumed. Except for nuclear power, the technology involved is state-of-the-art with very minimal engineering scaling. In addition, substantial advancements in high temperature superconductors, solid state transmitters and power conditioning equipment are expected. Such development makes this device a most competitive electric propulsion approach when it is fully developed. The concept can be demonstrated near-term as gauged on our rapid. limited resource progress.

The preconceptual design of a Space Orbiting Advanced Fusion Power Reactor (SOAR), which delivers up to 1000 MWe for at least 600 s from an orbited mass of about 500 tonnes, [b]was accomplished.^The power is produced by a magnetically confined D-3He plasma.[/b]^Approximately 96% of the fusion energy is in charged particles, and a direct converter has been designed which converts much of this energy into electricity at high net efficiency (about 80%).^An advanced shield design allows SOAR to deliver approximately 2 kilowatts of electricity for every kilogram of material orbited.^The shield is designed to absorb all rejected heat during operation, and no active radiator is required.^The SOAR reactor concept is designed to allow rapid startup and shutdown procedures.^The lack of radioactivity on launch and the low radioactive inventory after operation make the SOAR concept attractive from maintenance, safety and environmental perspectives.^The plasma physics approach extrapolates from the present plasma physics and fusion technology knowledge base using concepts which can be tested on existing or near-term devices.^The symbiosis of burst mode requirements, D-3He tandem mirror fusion reactor characteristics, and the space environment leads to a very high performance design concept.

I hope this gives you the idea of what the research that this thread mentions turned into once it was figured out. I also will say that they have made this reactor very small and very efficient. They mention a trip to Mars, that includes plenty of time on the surface, and a craft using one of these reactors in one of these links.[/quote]

I still have no clue as to what the latest tech is, but this stuff is really cool if you ask me. I am glad you posted the Mars info since that was one of the items that caught my eye.

Worldshadow, that is a great link to show what this would look like in real life. Thank you for posting that.

Through the Looking Glass with Phase Conjugation

Fall 1982
Los Alamos National Laboratory

Many times in my searching through hidden documents and talking to various people... the term "Digging a very deep Rabbit Hole" comes up...

When I was looking at the tech that would be involved in 'cloaking' a secret space ship or station, I was shown the secret of the 'Cheshire Cat' then told by the 'Rabbit' that asking about this information would attract the attention of "The Kings Men'  who wouldn't be able to put 'Humpty Dumpty' together again...

I have it from a private source that over the doorway to S4 at Groom Lake there is a 3D figurine of a Rabbit holding a Watch...

At first I thought this amusing... then I realized there was more to it...

In our Stargate threads we were shown a few documents that were very interesting... and led us to  the "Looking Glass"

Join me now as we follow 'Alice' into the 'Rabbit Hole' and step through the 'Looking Glass' at Los Alamos National Laboratory...

I would suggest d/ling this quickly... they already moved the Warp Drive papers

"I don't understand . . .' " said Alice. "It's dreadfully confusing!"
"That's the effect of living backwards," the Queen said kindly: "it always makes one a little giddy at first.. ''
"Living backwards!" Alice repeated in great astonishment. "I never heard of such a thing!"
- Lewis Carroll


Imagine a mirror that reflects more light than was incident, that reflects a beam into the same direction regardless of the mirror's tilt, that eliminates image distortions by causing light rays to retrace their paths as if running
backward in time, and that when looked at allows the observer to see absolutely nothing.

Science fiction, you say? Well, such mirrors have been the subject of intense investigation both here at Los Alamos and at other research laboratories around the world. Not only do they exist, but their practical applications may be far-reaching.

Active Shielding Concepts for the Ionizing Radiation in Space

Much ado has been made by various groups about the radiation hazards Astronauts would face in Space
Well it may not be an issue...
Lets have a look at a NASA contractor report

Contract NASw-502 Final Report Rev. 31 Jan. 1964

Space Sciences Laboratory
Missile and Space Division
Philadelphia, Pa.

Final Report
Contract NASw - 5 0 2
Period Covered: 1 Sept. 1962 - 31 Aug. 1963


Studies have been made on the problems of shielding a spacecraft from
ionizing radiation.Protons having energies between 100 and 1,000 MeV were taken as the radiation that should be excluded from the spacecraft's crew.
[b]An electromagnetic field system using a toroidal shaped spacecraft with a
confined magnetic field is shown to be the lightest among those treated.[/b]

In general, the active shield weight is only 20% that of the passive shield
for high energy protons and for large sizes of spacecraft. The shield with a confined field weighs 30% of that for a shield using an unconfined field. If hatches are included, the use of spherical modules leads to spacecraft that are lighter than spheres, cylinders, or toruses. For spacecraft in the shape of a torus, a passively shielded hatch is not required because there are no junctions between oppositely directed magnetic fields. In that case, a spacecraft in the shape of a torus is lighter than the other shapes.

Mr Chechov! Raise Shields....
So THIS is where Gene Roddenberry got his material... Time frame is right on the mark

this caught my eye,a "toroidal"......

.......look familiar!??

"with a confined magnetic field" 

a contained magnetic field is another way of saying,a self generated magnetic field.
what kind of space craft has the ability to generate its own magnetic field?,especially early in the 1960's!

In this post, Fusion Reactor, at ATS  we see the 'business end' of a big fusion reactor... Well I came across another document that has a similar sketch...

What are we talking about here?

Nuclear Power in Space...

Here is a list of spacecraft carrying nuclear power...

But the main focus of this document is the Nuclear Power plant for the Moon Base.... Here is a sketch from the paper... It is interesting to note that they felt the need to cover the structures with camouflage

Originally posted by jra Post ID 3742077

I was also going to make a comment on the "camoflaged" bit there. Actually zorgon, what they felt the need to do was to cover their structures with rigolith to add extra themal and radiation protection. Not to hide them, if you look at the colour version of the painting, you can see clearly that there are dishes on the top, like coolhand pointed out and lights all over the place, not to mention a giant solar panel being constructed. So it's clearly not meant to be camoflage.

I also notice that the image in the .pdf has been edited. There's an added structure to the top left, which isn't in the original painting. I find that a bit odd.
